I have K&N Filters on all my other vehicles and decided to check if one were available for my '87 Mercedes 560SL. Sure enough, it was available. Should have checked before. I've been a K&N fan since I first started using them on my motorcycles back in the late '70's. Great product, perfect fit every time. With the Recharger kit allowing me to clean and re-oil the filters when necessary, I can't imagine why anyone would use anything else to ensure their vehicles were operating at top performance.
